Funcation math word problems.. Help?!?

For each representation

1. Determine whether the function is quadratic, cubic, exponential, or logarithmic.
2. Find a symbolic representation of the function.
3. Answer the two questions that follow the representation. Show all work.

B. The following data shows the approximate number of thousands of metric tons of palm oil produced by Indonesia y as a function of the years since x

Years since Since 1965 = x Palm Oil Production=y

x=0 y=174
x=1 y=188
x=2 y=203
x=3 y=219
x=4 y=237
x=5 y=256

3a) if this pattern continued, how many thousands of metric tons of palm oil did Indonesia produce in 1977?
b) What is the radius of the snowball, if mass is 4000?
